  • What are the two methods of cloning plants mentioned in the video?
    Cuttings and tissue culture
  • What is the significance of asexual reproduction in cloning plants?
    It produces genetically identical organisms called clones.
  • Why are clones advantageous compared to offspring produced by sexual reproduction?
    Clones have predictable characteristics, unlike varied offspring from sexual reproduction.
  • What is the process of taking cuttings to clone a plant?
    • Remove a small piece of the plant
    • Dip the end in rooting powder
    • Rooting powder contains plant hormones that encourage root development
  • How does tissue culture differ from taking cuttings for cloning plants?
    Tissue culture divides a plant into many pieces, while cuttings involve a single piece.
  • What role do plant hormones play in tissue culture?
    • Stimulate growth
    • Encourage development into fully grown clones
  • Why must the conditions for tissue culture be sterile?
    To prevent the introduction of harmful microorganisms.
  • What are the benefits of tissue culture in commercial plant nurseries?
    • Produces thousands of genetically identical plants quickly
    • Cost-effective method for growers
    • Ensures desired characteristics in plants
  • How is tissue culture used to preserve rare species of plants?
    It allows for the cloning of rare species to ensure their preservation.
